Abstract
Process for producing para-xylene are described. The processes utilize a dual raffinate approach. Two raffinate streams from the adsorption separation unit are fed to the raffinate distillation column independently to take advantage of the differing desorbent concentrations in the two raffinate streams. The process yields significant reboiler duty savings and a reduction in overall fired fuel needed.
